The invention is directed broadly to a material being stitched is formedinto a tube about a worksupporting arm and is fedofi from the arm as itis stitched. A trimmingmeohanism is provided; for trimming the edges ofthe fabric which are to be stitched together. 7 nism includes aplurality of needles and complemental stitch formingmechanismcooperating therewith beneath the fabric and the thread layinglinger cooperating therewith above the fabric, so that'the trimmed edgesare joined by the united lines of stitching. The operating parts of themachine above the fabric are supported by an overhanging arm which ispreferably of .sleeve form, thus forming a hollow housing.

Located in this hollow housing is a rock shaft for reciprocatlng theneedle bar, a rock shaft for actuating the movable blade of the trimmingmechanism and the thread finger, and a rock shaft which may be os- Vcilla-te'd for lifting the Presser foot and lifting the trimmingmechanism from the inaterial. -The actuating members between-thesevarious rock shafts and the parts which are operated thereby, are, -forthe most part,

The machine contains three needles indicated at 34 in the drawings withwhich-is associated the usual needle guard. Coop crating with thesethreeneedles beneath they work support is a single looper 35. The

looper 35 is mounted on a looper'shaft 36 which extends lengthwise ofthework sup-v orting arm 9 and is mounted in suitable earing's formedtherein. This looper shaftis oscillated and is moved endwise by means ofa link-37 whichcooperates with a crank 38 on' the main shaft 7 This link37is pivotallyconnected to an arm 39 mounted in anoscillating bracket10, so that the upper end .of the link moves in an elliptical path,

Theneedle bar ,in its, reciprocation'sdoes not pass above the top bearing 54 so that the needle barat theupper portion thereof is continually housed, Within the hollow head.Extending lengthwise of the overhanging arm 3 is a rock shaft 56. Saidrock shaft is mounted in the bearings 57, 58' and 59, all of which areformed as a part of the overhanging arm. This permits the overhangingarm to be bodily shifted after the manner 7. above described withoutcreat-I ing anybind on the rock shaft 56 This rock shaft 56 is providedwith an arm 60,

which carries a ball stud at its lower end 61. A'pitman 62 is connectedto the ball stud at its upper end and is connected to a crank 63 at itslower end, which crank is formed as'a part of the mainshaft 7. As themainshaft rotates, the crank through this pitman 62 will oscillatetherock shaft 56. On the/outer end of the rock shaft 56 there is anarm 64.This arm 64 (see Fig ures2land 3) is connected by means of a link 65 toa lug formed as a partof a sleeve 66 which in turn is clamped to theneedle bar. 'As' the rock shaft oscillates, it will oscillatethe arm 64,and this will reciprocate the needle bar.

The material isheld onthe work support by a. presser foot 67. Thepresser foot 67 iscarried by a presser bar 68. The presser bar 68 ismounted in the bearings 69 and 70 at theupperv and lower ends,respectively, of the needle head. Mounted on the presser baris a collarwhich is provided with a forked arm 71, and-this forked arm 71 straddlesa guide bar '72 which is mounted in the bearing 7 0. The guide barisstationary and the forked arm 71 moves up. and down 'thereon.'- Thepurpose of the guide baris to cooperate with the presser bar inpreventing the presser foot from turning laterally. This is essential inview of the fact that the trimmingmechanism which-will b 1 describedlater, includes a stationary trimming-blade mounted on the presser foot.The presser bar is raised by means ;of a-rock shaft 78 which ismountedin suitable bearings in the overhanging arm and is provided with acollar 74 at its inner end. Said'collar is in turn provided with an arm75 which projects through a slot 76 in the cover plate 77 secured to threar side of the overhanging arm..

The housing 5 and the bracket 2; are preferably cast integral. Thecovering plate 77 for the overhanging arm aids in the assembling of thepitmans or eccentric strap. The cover plate 109 is for the'purposeofcovering an opening in the end of the overwhi'ch facilitates the placingof the rock shafts in their bearings, and a cover plate 110 at the upperface of the overhanging arm aids in giving access to the parts whichconnectthe pitman and the eccentric strap to the-rock shafts. A coverplate 111 covers an opening in the inclined housing 5 which gives accessto the crank and the eccentric onthe main shaft and also aids in theassembling of the eccentric strap and the pitmam The threads for the'machine are led through thread guides formed in a bracket 112. 7 Asillustrated in the drawings,'there are five threads, one for each of theneedles, one for the looper, and one forthe'thread laying fingeror'hook. The bracket 112, therefore, has five thread eyes,:threadeyes'are located one above the other in a verticalline. Mounteden the-frontof the overhanging arm 3 is, a supporting bracket 113. Fixedto this :supporting bracket 113 are five'tension posts, each of which issupplied with a pair of tension disks and spring tension means which maybe of the usual construction. The bracket 113 is pr'ovided with threadeyes indicated at 114, arranged-one above" the other, through whic thethreads pass after leaving the thread" eyes in the bracket 112. There isone thread eye 114 for each pair of tension disks, andthese thread eyesare located slightly'belowthe respective tension disks 'withwhich theyare associated. Directly opposite the thread eyes 114 is a series ofthread eyes 115, one for each thread. It will be noted that the threadpasses through the thread'eye 114, then up wardly and between thetension disks, and

thence downwardly and through the thread eye115; By this arrangement ofthread eyes and tension disks, gravity w'll aid in holding the threadbetween the tension disks, even after the tension disks are separated torelease the tension on the thread.

The plate is also provided witha series of arms :125'which are normally located directly beneath therespective tension disks. The upper edge of each arm 125 is beveled sothat when the arm is moved upwardly bythe lifting of the plate 123, saidarm will pass between the'tension disksand separate the tension disks soas to release the threads from tension. Inasmuch as the arms 125 arebeneaththe tension disks, gravity will aid in the moving of the armsaway from the tension'disks. This plate 123 is raised by means ofanarm126 which projects through a slot 127 into the interior. of theoverhanging arm.
